摘　　要：为研究散养条件下饲粮有效磷（AP）水平对北京油鸡产蛋鸡生产性能和鸡蛋品质的影响,选取630只体重无显著差异的19周龄北京油鸡蛋鸡,随机分为6组（组3～8）,每组105只,均饲以玉米-豆粕型基础饲粮,饲养在专门的散养舍内。20～21周龄饲粮钙水平为2%,22～57周龄饲粮钙水平为2.75%。组3～8饲粮AP水平分别为0.14%、0.19%、0.24%、0.29%、0.34%和0.39%。测定22～43周龄及44～57周龄内各组平均采食量、产蛋率、产蛋重、料蛋比、死淘率,以及37、57周龄时的鸡蛋物理品质。综合生产性能和鸡蛋品质结果,建议散养条件下22～43周龄北京油鸡产蛋鸡适宜的AP水平为0.29%,44～57周龄北京油鸡产蛋鸡适宜的AP水平为0.19%。To study the effects of dietary available phosphorus （AP）levels on production performance and egg quality of Beijing You chicken （BYC）under free range system,630 BYC laying hens with no significant difference in body weight at 19 weeks of age were chosen and randomly allocated to 6 groups （groups 3 to 8）,105 birds per group,fed with corn-soybean meal basal diet, and raised in free-range houses. The dietary calcium level was 2.0% for 20 to 21 weeks of age, 2.75% for 22 to 57 weeks of age. Six dietary AP levels were 0.14%, 0.19%, 0.24%, 0.29%, 0.34% and 0.39%,respectively. Average feed intake,laying rate,egg weight,feed-egg ratio,mortality rate were calculated from 22 to 43 weeks of age and 44 to 57 weeks of age, and egg quality indices at 37,57 weeks of age were measured. The results suggested that under free range system,the appropriate dietary AP level was 0.29% from 22 to 43 weeks of age,and 0.19% from 44 to 57 weeks of age for BYC laying hens based on production performance and egg quality.
